One way of getting a good idea when it's possible to plant calendula is to use the USDA zone info for Woodlake.

Planting Calendar for Calendula

When to plant:	Up to 5 weeks before last frost.

Since calendula are moderately cold tolerant you can plant them a little earlier in the year than other plants that might not handle the cold.

The earliest that you can plant calendula in Woodlake is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant calendula and expect a good harvest is probably October. You probably don't want to wait any later than that or else your calendula may not have a chance to really do well. Starting your calendula indoors is a great way to get them started a couple of weeks earlier.
